Description

The The invention relates to deodorant or antiperspirant sticks based on an ethanol-containing oil-in-water dispersion for application of water-soluble Active ingredients on the skin.

Commercially available deodorants and antiperspirants are mostly used as sprays or as a pen assembled; There are also roll-on preparations and creams on the market. Many pen-shaped Antiperspirant preparations are formulated as anhydrous suspension sticks. Leave such preparations the user a pleasantly dry skin feeling after application. A effective release of the water-soluble antiperspirant active ingredients from such preparations is however limited (see Chemistry and Technology of the Cosmetics and Toiletries Industry, Ed .: D.F. Williams and W.H. Schmitt, London: Blackie, 1996, 2nd edition, p. 326), and it is usually not the appreciated by many consumers fresh feeling achieved. The anhydrous preparations, in particular such on the basis of volatile Silicone oils, have the disadvantage that the dispersed active substances are easy to visible product residues Lead skin and clothing. Furthermore such preparations are relatively expensive, since the oil components as a drug carrier more expensive than water. Under the pressure load in the application it happens often to a oiling out, which reduces the cosmetic acceptance of these preparations in the user.

With respect to anhydrous sticks, as are known, for example, from WO 94/24997 A1 and WO 00/67713 A1, have emulsion sticks, as described, for example, in WO 98/17238 A1, EP 281 288 A2 . DE 2 335 549 . US 4,725,431 . EP 617 952 A1 and EP 291 334 disclosed, several advantages. Replacement of the wax and oil additives with water makes the emulsion sticks less expensive to produce. The emulsified waxes impart a soft, light skin feel, and finally, water-soluble cosmetic active ingredients (ie in particular also antiperspirant active ingredients) can be more easily delivered to the skin since they are already present in dissolved form in the aqueous phase of the emulsion.

The Emulsion sticks of the cited prior art are based formulated in a water-in-oil dispersion, the water-soluble Active substances are therefore present in the inner, dispersed phase and have to migrate through the outer, lipophilic layer after application, to reach their place of action on the skin. Thus, the known water-in-oil emulsion sticks similar in terms of drug availability Disadvantages on how anhydrous suspension pencils.

DE 19749819 A1 discloses water and oil containing, wax-free antiperspirant sticks based on an oil-in-water emulsion. Such pens have inadequate cosmetic properties, leave unpleasant sticky and visible residues, and show insufficient stability for prolonged use. An example with glycerol monostearate as W / O emulsifier and octyldodecanol as an oil component has a medium-firm consistency and a greasy feel on the skin and begins to soften even at 50 ° C.

In WO 99/59537 A1 are water-containing, oil-free deodorant pens Base of a (lipid or oil) in water emulsion discloses the wax components having a melting point> 50 ° C, nonionic water-in-oil emulsifiers, a nonionic oil-in-water emulsifier containing an HLB value greater than 7 and a polyol. Farther in this document are microemulsion-containing and PIT-emulsion-containing Deodorant sticks, the wax components having a melting point> 50 ° C, non-ionic water-in-oil emulsifiers, a nonionic oil-in-water emulsifier with an HLB value of more than 7 and at 20 ° C liquid oils. Such pens also have insufficient cosmetic properties unpleasant sticky and visible residue and show one for prolonged use insufficient stability.

WHERE 02/083091 A1 discloses structured antiperspirant compositions in the form of an oil-in-water microemulsion. The structural difference between these compositions and the oil-in-water dispersion sticks The present invention is particularly clear by the high Proportion of unfavorable according to the invention Silicone and hydrocarbon oils.

WHERE 02/017870 A2 discloses hydrous antiperspirant sticks which a siliconized polyamide as Konsisienzgeber or Structurant contain.

WO 02/032914 A1 discloses water-containing antiperspirant sticks, the acylated cellobiose as Konsis supplier or Structurant and a high proportion of inventively unfavorable silicone and hydrocarbon oils.

In the publications DE 199 62 878 A1 and DE 199 62 881 A1 are disclosed deodorant or antiperspirant creams based on an oil-in-water emulsion having at 21 ° C a viscosity of at least 50,000 mPa · s, preferably in the range of 200000-1500000 mPa · s, that is, they are present in viscous to highly viscous pasty form. These creams contain wax components with a melting point> 50 ° C, nonionic water-in-oil emulsifiers, nonionic oil-in-water emulsifier with an HLB value of more than 7 and a polyol. As soft creams, they can be applied either only with the fingers, which is rejected by many consumers as impractical, or the creams must be filled in special applicators that are significantly more expensive than the pen cases for the deodorant or antiperspirant sticks of the invention. Would you like the in DE 199 62 878 A1 and DE 199 62 881 A1 compositions which have been heated and mixed after static and that is to say without stirring, would give pen-like compositions having generally unfavorable properties such as poor feel and / or lack of stability, for example phase separation or condensation, since the emulsifiers and the oils are not matched to each other as in the present invention.

It It was therefore the object of a deodorant or antiperspirant composition to develop, which is suitable as an effective carrier for water-soluble active ingredients and allows a rapid release of the drug on the skin.

A Another object was to provide a deodorant or antiperspirant composition to develop with excellent cosmetic care properties.

A Another task was a deodorant or antiperspirant stick to develop on the one hand a high stability, that is strength, on the other hand but has a pleasant release behavior, so not too tight is, but slightly over to have the skin painted while giving off a sufficient amount of product.

A Another object was to provide a deodorant or antiperspirant composition develop as little sticky as possible when applied to the skin or visible residue leaves behind.

A Another object was to provide a deodorant or antiperspirant composition to develop a cooling when applied to the skin or refreshing skin sensation generated or leaves.

A Another object was to provide a deodorant or antiperspirant composition to develop as possible little visible residue on the clothing that comes into contact with the treated skin leaves behind.

A Another object was to provide a deodorant or antiperspirant composition to develop, which can be easily washed off the skin.

A Another object was to provide a deodorant or antiperspirant composition with a favorable economic and application technology Cost-performance ratio too develop.

The Lipid or wax component with a melting point> 50 ° C forms with the / the oil (s) and possibly further higher melting Lipid or wax components a gel matrix containing larger amounts absorb water, ethanol and polyol. These structures, stabilized by certain amounts of water-in-oil emulsifiers and oil-in-water emulsifiers are left behind because of their water and especially theirs Ethanol content when applying a fresh, cooling Impression. The emulsifiers are thus coordinated, that the stick compositions according to the invention in the form of an oil-in-water dispersion available. Without wishing to be bound by this theory, it is believed that the oil-in-water emulsifiers together with part of the water-in-oil emulsifiers lamellar liquid crystal phases form with a portion of the water to a hydrophilic gel phase being constructed. This hydrophilic gel phase surrounds the aqueous bulk phase. In this aqueous In turn, bulk phase are the lipophilic components surrounded by a lipophilic gel phase derived from the water-in-oil emulsifiers with a part of the oil-in-water emulsifiers and some water is formed, dispersed.

Of the Antiperspirant active ingredient is in the outer, continuous aqueous Phase solved, so that a significantly improved and more efficient drug delivery in comparison to the known anhydrous suspension pencils and Water-in-oil emulsion sticks results. This drug release is indirectly very good determine over the measurement of the electrical resistance of the respective product. The exact measuring arrangement and the implementation of the measurement are as follows described below. The pins according to the invention accordingly have one electrical resistance of a maximum of 300 kΩ, preferably of a maximum of 100 kΩ and particularly preferably of not more than 80 kΩ. WO 98/17238 A1 however, disclosed pins have an electrical resistance of more than 3000 kΩ.

The Solidification of the deodorant or antiperspirant sticks is not based on soap gels or fatty acid salt gels, taking in fatty acids Alkane, alkene and alkyne acids having at least 4 carbon atoms substituted, for example with hydroxyl groups. In a particularly preferred embodiment are the deodorant or antiperspirant sticks free of soap gels, respectively Fatty acid salt gels, in particular free from lithium, sodium, potassium, ammonium, diethanolamine and triethanolamine salts of fatty acids.

The Solidification of the deodorant or antiperspirant sticks is not based on inorganic and / or organic polymeric hydrogel formers, such as celluloses, Cellulose derivatives, for example hydroxyalkylcelluloses, polyacrylates, Veegum or Bentone. In a particularly preferred embodiment are the deodorant or antiperspirant sticks free of inorganic and / or organic polymeric hydrogel forming gels.

Next the cheap Release of active substance brings the packaging as an ethanol-containing oil-in-water dispersion other benefits. For one thing, the composition can be light be washed off the skin. On the other hand forms at or after applying to the skin together with the skin moisture a nourishing oil-in-water cream, the a refreshing, cooling skin feel generated.

Surprisingly, and unforeseeable for the skilled worker, it has been found that the oil components and the water-in-oil emulsifier or the water-in-oil emulsifier mixture must be matched with respect to their solubility parameters in order to provide stick compositions with satisfactory performance To form hardening.
